" FREDERICK G. FARR, OF NEW YORK, N. Y.

HYDRAULIC OIL-DlELllIVJERY SYSTEM.

Application filed February 9, 1922. Serial No. $115,423.

To all whom it may concern:

Be it known that I, FREDERICK G. FARR,

a citizen of the United States of America, residin at New York city, in the county of New ork and State of New York, have in vented certain new and useful Improvements in Hydraulic Oil-Delivery Systems, of which the following is a specification, reference being had therein to the accompanying drawings.

he invention relates to hydraulic oil storage and delivery systems and is more particularly designed for use upon boats and in other places Where head room is limited. It

isthe object of the invention to obtain a con head which would displace all of the water in the tank and where the ratio of the gravities of water and oil is twelve to sixteen, the height of this filler above the bottom of the tank must be one-third greater than the height of the water head thereabove. If,

however, head room is limited as in boat constructions, such an arrangement is not possible.

My improvement consists in a construction wherein a filler which does notextend above the deck level can be used for displacing all of the water in the tank extending up to the deck, the construction being as follows:

The drawing shows diagrammatically a longitudinal section through a boat in which my improved system is installed.

. A is the hull of the boat, B the deck therefor, C the oil storage tank, which is arranged below the deck, but extends upward as close as possible thereto. D is the water displacement conduit which is connected with the bottom of the tank and is provided with the usual trap portion E. The normal head of water is equal to the level of the top of the tank, but an auxiliary drain connection F is provided some distance below this level. G is the oil fill connection, the top of which is at the deck level, but which extends downward into the tank to a point below the level of the auxiliary drain F. H is the oil delivery conduit which has a screen I at its entrance and located just below the top of the tank and which will prevent the passage of water therethrough.

.. With the construction as thus far described, in order to originally fill the tank, water is first admitted thereinto from the water head, which will completely displace the air and completely fill the tank with water. The auxiliary drain'F is then opened by the operation of a valve J and oil is then fed into the filler G. When the valve J is opened, the level of water in the filler conduit G will drop to that of the drain and the elevation of the top of the filler above this point is sufficient so that the head of oil will displace the remaining water in the filler G. As soon as the oil is freed from the conduit G, it will pass upward through the water to the top of the tank and this will continue until the water is displaced to the level of the lower end of the filler. From that time on the oil will merely displace the water without passing through the same until the entire tank is filled. The auxiliary drain connection F is then closed and the oil is delivered from the tank by the full water head, which is suflicient to raise it the required distance above the deck level.

\Vhat I claim as my invention is:

1. In a hydraulic oil storage and distribution system, the combination with a storage tank. of a water head equal to the height of said tank, a valve-controlled water drain below the top of the tank, and an oil fill conduit connecting to said tank at a point below the level of said drain, for the purpose described.

2. In a hydraulic oil storage and distribution system, the combination with a storage tank, of a water head and oil filler approximately at the level of the top of said tank. a valve-controlled water drain below the top of the tank, and a connection between said oil filler and tank below said water drain.

3. In a hydraulic oil storage and distribution system, the combination with a storage tank, of a water head equal to the level of the top of said tank, a screened oil discharge located at the top of said tank, a valve-controlled water drain below the top of the tank, and an oil filler extending downward in said tank to a level below said drain.

In testimony whereof I aflix my signature.

FREDERICK Gr. FARR.
